Monitor your Unreal Engine mobile app

Our New Relic Unreal Engine Plugin monitors your Unreal Engine mobile app and provides deep insights into your app's performance, errors, and user experience. Once you install and configure the Unreal Engine Plugin, you'll be able to:

  • Capture C++ errors: Quickly identify and fix problems.
  • Create custom events and metrics: Understand how your users interact with your app.

Manual installation

If you need to install the plugin manually, follow the steps below.

Review the requirements

Before you install the Unreal Engine Plugin, make sure your Unreal Engine app meets these version requirements:

Add the agent to your project

  1. In your project's root directory, create a folder named Plugins.
  2. Copy the NewRelic folder on Github. You should have something like
├── Plugins
└── NewRelic
└── NewRelic.uplugin

Click Restart Now to continue with additional configuration.

To allow interfacing between the agent and your C++ code, add NewRelic to the list of dependencies in your game module’s .Build.cs file:

Add application token(s)

To authenticate your Unreal Engine app's data with New Relic, add your application token(s) using one of these options:

  • In your project settings under Plugins → NewRelic, paste your app tokens(s) in the New Relic App Token field(s). If you want to have separate New Relic mobile apps (one of Android and one for iOS), then you'll need to add both app tokens.

Monitor C++ errors

In the New Relic UI, you can view your fatal and non-fatal C++ errors and handled exceptions, including details like event trails, attributes, and stack traces for each recorded error.

To view your errors:

  1. Go to one.newrelic.com > All capabilities > Mobile.
  2. Select your Unreal Engine app.
  3. Click Exceptions > Handled exceptions.

You can also build a dashboard for these errors using this query:

SELECT * FROM MobileHandledException SINCE 24 hours ago
